| 摘 要： | 在室温下(17~19℃),通过接种成熟的亚硝化颗粒污泥于缺氧-好氧连续流反应器中,研究连续流亚硝化颗粒污泥的启动及稳定运行.结果表明,在启动阶段,颗粒污泥系统的亚硝态氮积累率(NAR)平均超过95%,成功启动了缺氧-好氧连续流亚硝化颗粒污泥系统.将好氧区溶解氧(DO)由(3±0.2) mg·L~(-1)提高到(4.5±0.2) mg·L~(-1),探究DO对于该连续流系统的影响.结果表明,在较高DO下,缺氧-好氧连续流亚硝化颗粒污泥系统仍能保持良好的亚硝化性能,平均NAR大于95%.另外,通过改变进水的水力停留时间(HRT),探究HRT对于该连续流系统的影响.较短的水力停留时间(8.4 h)会加快污泥颗粒在系统中的循环,使破碎的颗粒污泥不能及时重组,致使污泥颗粒沉淀性变差,造成污泥颗粒的流失.HRT增加到12.2h时,颗粒污泥系统得到了恢复,并且可以稳定运行.在运行末(166 d),氨氮去除率和NAR分别为86.7%和96.2%.
